AMC 12 B 2015

Lol @physicsdeity‌

I thought that it was okay…
anyone who wants can pm me

Wait darn am I the only one who thought this test was incredibly easy? For me 1-19 took about 40 minutes altogether (I decided to spend the rest of my time checking my work, and considering my score, that was a bad decision).

In particular, I thought this test was loads easier than the (already quite easy) 12A. I’m almost certain the cutoff will be set at 100.

I last-ditched guessed 20, got it wrong, and missed question 10 (derp) for a final score of 115.5

Also I believe we can discuss the test today since it’s no longer the 25th (and discussion yesterday wasn’t allowed AFAIK)

@DVA6102 what were your answers on the ones that you did?

I think I did better than the last time. Solved 22 problems, but made a stupid mistake on #10, and apparently guessed that last one correctly. Blanked on 20 and 24. (24 was literally the easiest problem on the planet if you just draw it out; don’t know why I didn’t attempt it.) Hoping for 135.

Easier. Solved 21 problems, got #10 wrong. 23 and 24 I had answers to but didn’t want to risk.

Hoping for 126.

Nice job… do you think a 215.5 will make USAMO (115.5 + 10*10)

and @willdbk I don’t have my test booklet since we weren’t allowed to keep. I’ll be getting it back from the school later today though.

What was the answer to 10

@DVA6102 I’m pretty sure a 215.5 would make it.

@willdbk 5 triangles satisfied the given condition

I always miss those kinds of questions, like the problem on the 12A about tangent lines to 2 circles, so I considered putting 5 just because I probably missed a case. lol

question 10 was very un-creative since a very similar question appeared on last year’s 12B as well (though I may be slightly biased since I got both of them wrong) :stuck_out_tongue:

and yeah I missed that on the A oops

just saw that question on the 2014 12B, totally would’ve gotten that wrong lol

Is the answer key out yet

I am fairly sure I got a 112.5 Made a silly though…mighta gotten me into distinguished honor roll

agghhh i missed a triangle on #10 so now my score is 94.5, I was so close to AIME :frowning:

How did you guys get the answers??? Help please!

They all aren’t up. I have the booklet but not the answers.

Answers are up - for some reason #18 isn’t listed. What’s the answer for it? I’m dying to know because that’s the difference between 105 and 99
